America may not have its own royal family, but an 18-room Colonial mansion in northern Fairfield is fit for a queen ... and a king. Not just because of the regal-sounding name of the street on which it is located, but because the architect seamlessly incorporated disparate design tastes of the homeowners making it truly "his and hers." The couple had the white-washed brick house at 205 Queens Grant Drive custom built in 1998, specifically asking the architect to make sure the structure reflected both their interests, accommodating her preference for classic style and his for contemporary.

The result is the perfect blend of elegance and relaxation. "There is a formality to it but also practicality in the size of the rooms and the Smart House features," said one person familiar with property.

The house sits in a setting that more resembles the English countryside than the town's Greenfield Hill area, where it sits on a 2-acre level property surrounded by acres of open space. Adding to the charm is the formal English garden in the backyard near the formal in-ground pool area with fountains and a spa.

There is nothing to obstruct the view of this stunning property or of the surroundings. All the utilities are underground.

The property comprises 10,500 square feet of living space, most of that in the main house but the pool house is sizable too and could function as a guest house. It has a vaulted ceiling, skylights, full bath, petite kitchen, fireplace, washer and dryer, screened porch and its own heating and cooling zone.

Many of the features incorporated into this house are rare and remarkable. It has Versailles patterned leather flooring in the lower level billiard room with a back lighted bar that has black onyx and stainless steel counters. On the main floor there is a circular Tanglewood conservatory off the spacious gourmet kitchen. The conservatory provides a casual dining room designed to bring the outdoors inside. It has a fireplace with a custom stone mantle, limestone flooring with radiant heat, and electronic shades. The his and hers master bathrooms and lower level of the house also have radiant heated floors.

Most of the rooms have antique chestnut floors and the custom front door is also made from antique chestnut. All six bedrooms, including the first floor guest room and the in-law suite in a separate second floor wing, are en suite. There are marble fireplaces in the library and living room. Many rooms have French or other doors to the rear bluestone and red brick patio and/or the front verandas.

Gourmet kitchen features include a butler's pantry, granite counters, two-tiered center island, pendant lighting, and sliding doors to the patio. It has an oversized Sub-Zero refrigerator, six-burner Wolfe range with double ovens and warming drawer, and Miele dishwasher.

The family room has a cathedral ceiling with exposed wooden beams and floor-to-ceiling stone fireplace. The mudroom features slate flooring, custom pine lockers, storage, two built-in dog cubbies and access to the three-car garage and second-floor in-law suite, which could be used as an office. This suite also has custom track lighting, sliding door to a balcony, skylight, and full bath with iridescent Italian glass tile floor and limestone vanity.

There is another large office in the master suite, which also features a coffered ceiling and marble fireplace. The two master baths have heated towel racks. There are three other bedrooms on this floor, all with built-in desk areas.

If family members and guests are scarce look for them in the lower level, which was designed with five distinct areas -- the billiard-bar room with four dishwashing drawers, ice maker, and petite wine refrigerator; a large home theater with large screen projection and reference grade video and sound, mechanical "darkening" shades, velvet curtains, and lounge with built-in casual dining area; game or secondary family room; craft room with a sink; and mirrored exercise room with a half bath.
